Abstract
Description
- 1. Technical Field
- The disclosure relates to a nozzle of an injection machine.
- 2. Description of Related Art
- In injection molding using an injection molding machine, nozzles with different lengths are needed to suit for different size injection molds. Thus, different lengths of heating apparatuses are replaced to support the nozzles, which is very inconvenient.
- Many aspects of the present embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an exploded, isometric view of a nozzle of an injection machine. -
FIG. 2 is similar toFIG. 1 , but viewed from another aspect. -
FIG. 3 is an assembled, isometric view of the nozzle ofFIG. 1 . -
FIG. 4 is a cross-sectional view taken along the line IV-IV ofFIG. 3 . - The disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
-
FIG. 1 andFIG. 2 show an exemplary embodiment of a nozzle of an injection machine. The nozzle includes amain body 10 and aheating apparatus 100 set around themain body 10. - The
main body 10 includes aconical nozzle head 11, acylindrical pole 13 connected to thenozzle head 11, and afixing portion 15 formed at one end of thepole 13 opposite to thenozzle head 11, for screwing into a discharge hole of an injection molding machine (not shown in the figures). Thepole 13 defines aslot 131 in an outer surface along an axial direction of thepole 13. - The
heating apparatus 100 includes aheating portion 20, afirst sleeve 30, and asecond sleeve 40. Theheating portion 20 is a helical-spring shaped electric heating piece, which is suitable for setting around thepole 13. Theheating portion 20 is compressible. A plurality oftabs 31 extend from a first end of thefirst sleeve 30 along an axial direction. Eachtab 31 defines afirst positioning hole 311.Internal threads 33 are formed on an inner surface of thefirst sleeve 30, adjacent to a second end opposite to thetabs 31. A ring-shapedfirst blocking portion 35 is formed on the inner surface of thefirst sleeve 30, adjacent to the first end. A ring-shapedsecond blocking portion 41 is formed on an inner surface of thesecond sleeve 40, adjacent to a first end of thesecond sleeve 40. Asecond positioning hole 42 is defined in a second end of thesecond sleeve 40.External threads 43, which are suitable for mating with theinternal threads 33, are formed at an outer surface of thesecond sleeve 40, adjacent to a second end of thesecond sleeve 40 opposite to thesecond blocking portion 41. -
FIG. 3 andFIG. 4 show that in assembling theheating apparatus 100, theheating portion 20 is received in thesecond sleeve 40. Thefirst sleeve 30 is coupled to thesecond sleeve 40, with theexternal threads 43 mating with theinternal threads 33. Theheating portion 20 is positioned between thefirst blocking portion 35 and thesecond blocking portion 41. Theheating apparatus 100 is set around thepole 13, for heating thepole 13. Apin 50 extends through thefirst positioning hole 311 to engage in theslot 131, for preventing thefirst sleeve 30 from rotating relative to thepole 13. Anotherpin 50 extends through the second positioning hole 411 to engage in theslot 131, for preventing thesecond sleeve 40 from rotating relative to thepole 13. - When fitting with another
main body 10 with a shorter length, thesecond sleeve 40 is rotated toward thefirst sleeve 30. Thefirst blocking portion 35 and thesecond blocking portion 41 compress theheating portion 20, to shorten theheating portion 20 and theheating apparatus 100, for suiting for the shortermain body 10. - When fitting with another
main body 10 with a longer length, thesecond sleeve 40 is rotated away from thefirst sleeve 30. Thefirst blocking portion 35 and thesecond blocking portion 41 release theheating portion 20 or theheating portion 20 is partly restored, to elongate theheating portion 20 and theheating apparatus 100, for suiting for the longermain body 10. - It is to be understood, however, that even though numerous characteristics and advantages of certain embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
